Definitions
- the primer of this invention is appropriate for adhering curable silicone compositions, particularly heat curable, to the surfaces of various organic materials.
- Silicone rubbers have an excellent heat resistance. For this reason, they have recently been used in a broad range of applications in which rubber elasticity is required at elevated temperatures.
- silicone rubbers are more expensive than general-purpose synthetic rubbers and general-purpose plastics and have slightly inferior properties, e.g., initial mechanical properties, steam resistance and chemical resistance, etc., compared to some synthetic rubbers and plastics.
- composite materials have been widely used in which the surface of a synthetic rubber or plastic is coated with a silicone rubber so the rubber or plastic material will not suffer from oxidative degradation by oxygen at elevated temperatures.
- a primer composition has been developed which can tightly adhere curable silicone compositions and particularly heat-curable silicone rubber compositions to various synthetic rubbers, plastics, and to inorganic materials brought into contact with the silicone compositions during cure.
- the primer composition is composed of three components.
- Component (I) consists of component (A) or (B).
- Component (A) consists ofyan organosilicon compound containing at least one epoxy group-containing monovalent hydrocarbon group, and at least one silicon-bonded lower alkenyl group or silicon bonded hydrogen atom in each molecule.
- Component (B) consists of a mixture of (a) an organosilicon compound which possesses silicon-bonded hydroxyl and silicon-bonded lower alkenyl radicals or silicon-bonded hydrogen, and (b) an organotrialkoxysilane containing at least one epoxy group containing monovalent hydrocarbon group.
- Component (II) comprises a trialkoxysilane or its partial hydrolysis product.
- Component III comprises an organotitanate ester.
- the present invention relates to a primer composition consisting essentially of Component (I) consisting of either (A) consisting of an organosilicon compound in which at least one A(RO) 2 Si group and at least one silicon-bonded lower alkenyl group or silicon-bonded hydrogen atom are present in each molecule where A is an epoxy group-containing monovalent hydrocarbon group and R is a lower alkyl group; or (B) consisting of a mixture of (a) an organosilicon compound which contains silicon-bonded hydroxyl group and silicon-bonded lower alkenyl group or silicon-bonded hydrogen atom, and (b) an organotrialkoxysilane with the general formula ASi(OR 1 ) 3 where A is as defined above and R is an alkyl group; Component II consisting essentially of a trialkoxysilane with the general formula R 2 Si(OR 3 ) 3 or its partial hydrolysis condensation product where R 2 is-a hydrogen atom or an organic group possessing an aliphatically unsaturated bond and R 3 is an alky
- Component (I) is the principal component of the primer composition of the present invention. It forms a cured film that tightly adheres to the substrate by an alcohol-liberating condensation with component (II) in the presence of ambient moisture and in the presence of catalytically active component (III).
- Component (I) consists of either component (A) or component (B).
- Component (A) is an organosilicon compound in which at least one A(RO) 2 Si group and at least one silicon-bonded . lower alkenyl group or silicon-bonded hydrogen atom are present in each molecule.
- A is an epoxy group-containing monovalent hydrocarbon group and R is a lower alkyl group.
- Each molecule of component (A) preferably possesses at least 2 epoxy group-containing monovalent hydrocarbon groups with the general formula R 6 is an arbitrary divalent organic radical for which concrete examples are the phenylene group, hydroxylated hydrocarbon radicals, the chloroethylene group, the fluoroethylene group, -CH 2 0CH 2 CH 2 CH 2 -, -CH2CH2OCH2CH2-, -CH 2 CH 2 OCH(CH 3 )CH 2 - and -CH 2 OCH 2 CH 2 OCH 2 CH 2 -.
- Other examples of A are-the beta-(3,4-epoxycyclohexyl)ethyl group and the gamma-(3,4-epoxycyclohexyl)propyl group.
- R are methyl, ethyl, normal-propyl, isopropyl, hexyl, and methoxyethyl.
- the methyl group is preferred.
- Concrete examples of the silicon-bonded lower alkenyl group are allyl, 1-butenyl and isopropenyl.
- Typical examples of the organosilicon compound include organosilanes and organopolysiloxanes. The molecular configuration of such an organopolysiloxane is straight chain, branched chain, cyclic or network.
- the degree of polymerization is equal to or greater than 2; however, it is preferably a degree of polymerization corresponding to an oligomer.

Test pieces are thus obtained in which the silicone rubber is tightly adhered on the above-mentioned adherend material. The test piece is repeatedly bent at its center 1000 times at an angle of 90°; however, the silicone rubber could not be peeled off from the rubber adherend.
- primer composition P-1 tetra(normal-butyl)titanate

Test pieces are thus produced in which the silicone rubber is tightly adhered to the adherend material.
- the silicone rubber layer was subjected to a tensile peeling force at 180° from the test sheet in which the silicone rubber was adhered to the adherend sheet. The results are reported in Table 1.
- Primer compositions P-1 and P-2 of Example 2 are coated on test pieces (30 mm (width) X 100 mm (length) X 3 mm (thickness)) of the vulcanizates of an EPDM rubber composition and of SE4306 and then air-dried at room temperature for 60 minutes.

Test sheets are thus obtained in which the silicone rubber is tightly adhered to the above-mentioned adherend materials. These test sheets are examined by the same adhesion test as in Example 1. The results are 100% cohesive failure in all test sheets.
